[0057] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0058] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0059] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0060] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0061] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0062] For ease of understanding, the following describes some aspects of the embodiments of the present invention:

[0063] like Figure 2 As shown, an embodiment of the present invention provides a policy management method, wherein the method is executed by a policy agent and includes:

[0064] S10, Obtain policy management request information for cloud-native virtual network functions sent by the operation support terminal; wherein, the policy management request information includes the requested operation information;

[0065] It should be noted that, as Figure 3 and Figure 4 As shown, when the Operator sends a cloud-native VNF policy management request (i.e., the policy management request information) to the 3GPP management system (executed by the Operation Support System within it), the 3GPP management system obtains the policy management request information and sends it to the policy broker. Specifically, the OSS (Operation Support Systems) / BSS (BaseStation Subsystem) (hereinafter collectively referred to as the Operation Support System) in the 3GPP management system transmits the policy management request information to the policy broker through the policy management interface exposed by the policy broker.

[0066] S20, invoke at least one first virtual network function general management function among multiple virtual network function general management functions that can perform the operation corresponding to the operation information;

[0067] It should be noted that, as Figure 4As shown in section 3.4, the policy invocation request is initiated. The policy broker interacts with the relevant GOF (Generic OAM functions) through an interface, invoking the required GOF (the first virtual network function's generic management function), and sending the policy decision results to the relevant GOF. Specifically, for example, in this traffic-related embodiment scenario, the policy broker sends the policy decision results and commands to the traffic executor, which can then drive the execution of specific traffic control operations. In the configuration management scenario, the policy broker sends the policy decision result commands to the configuration-related GOF.

[0068] S30, after obtaining feedback information of the corresponding operation of the first virtual network function general management function executing the operation information, send the feedback information to the operation support terminal;

[0069] It should be noted that, as Figure 4 As shown in Figure 4.2, the first virtual network function general management function returns the implementation result (i.e., the feedback information) to the policy broker; 5.1, the policy broker directly notifies the OSS / BSS (i.e., the operation support terminal) of the 3GPP management system of the implementation status of policy management, that is, sends the feedback information, and then transmits it to the operator. Optionally, the policy broker may also indirectly send the implementation information of policy management to other entities that can receive notifications, and then forward it to the 3GPP management system (OSS / BSS), and then transmit it to the operator.

[0070] In this embodiment, after obtaining the policy management request information of the cloud-native virtual network function sent by the operation support terminal, the first virtual network function general management function that can execute the operation information corresponding to the operation information in the policy management request information is invoked. After obtaining the feedback information of the first virtual network function general management function, it is sent to the operation support terminal, thereby completing the cloud-native network function policy management. This avoids heavy reliance on complex MANO system functions, simplifies management and reduces system maintenance costs in the face of cloud-native technology evolution.

[0071] Optionally, the method further includes:

[0072] Obtain a list of general management functions; wherein, the list of general management functions includes general management function identifiers of the virtual network function general management functions that can perform operations corresponding to multiple operation information; the general management function identifier includes a general management function identifier number of the corresponding virtual network function general management function and a general management function description field of the corresponding virtual network function general management function;

[0073] Based on the general management function list and the operation information requested by the policy management request information, obtain the corresponding first virtual network function general management function.

[0074] In this embodiment, the policy request information includes at least one of the following: a list of GOFs for policy management targets, i.e., the list of general management functions: including GOF identifiers related to the request (i.e., general management function identifiers), each identifier being represented by a combination of a GOF identifier number (i.e., the general management function identifier number of the first virtual network function general management function) and a GOF description field (i.e., the general management function description field of the first virtual network function general management function); policy management information: including information on specific management-related policies (i.e., the operation information), for example, in a traffic management scenario, such as limiting traffic to a specific set of VNFs / VNFCs (Virtualized Network Function Components) during upgrades, ensuring that only specific traffic is directed to a certain set of VNFs / VNFCs during upgrades, thereby minimizing the impact on normal services; in a configuration management scenario, such as including routing policies, security policies, and configuration resource limits, etc.

[0075] Optionally, the method further includes:

[0076] Based on the policy management request information, determine whether there is a policy management conflict when multiple first virtual network function general management functions execute the operation corresponding to the operation information, and obtain a first determination result;

[0077] If the first determination result is negative, at least one of the general management functions for calling multiple virtual network functions that corresponds to the operation information is executed.

[0078] In this embodiment, such as Figure 4 As shown in section 3.1, the policy broker determines whether to allow a policy management request for the GOF, including judging whether there is a policy management conflict when multiple first virtual network function general management functions execute the operation corresponding to the operation information, and obtaining the first judgment result. If the evaluation meets the relevant conditions for the policy request (i.e., if the first judgment result is negative), the policy broker will interact with the relevant GOF (the first virtual network function general management function) through an interface, call the required GOF, and send the policy decision result to the relevant GOF. Specifically, for example, in this traffic-related embodiment scenario, the policy broker can drive the execution of specific traffic control operations by sending the policy decision result and command to the traffic executor. In the configuration management scenario, the policy broker sends the policy decision result command to the configuration-related GOF.

[0079] Optionally, the method further includes, when the first determination result is yes:

[0080] Modify the operation information to obtain corrected operation information;

[0081] The correction operation information is used as the operation information for the general management function of the first virtual network function.

[0082] In this embodiment, if it is determined that there is a policy management conflict when multiple first virtual network function general management functions execute the operation corresponding to the operation information, it is necessary to modify the operation information, obtain the corrected operation information, and use the updated operation information as the operation information of the first virtual network function general management function, and as the basis for calling the first virtual network function general management function to execute the operation.

[0083] Optionally, the method further includes:

[0084] Send a policy request response to the operation support terminal; wherein the policy request response includes the correction operation information.

[0085] In this embodiment, the policy broker returns a response message to the OSS / BSS (i.e., the operation support terminal) in response to the policy management request. The response message is used to instruct the policy broker to allow or deny the operation on the specified policy management request. Optionally, if the policy broker needs to adjust the management policy carried in the policy request, it carries the adjusted management policy information in the response message. Here is an example: when the policy conflict is specifically caused by traffic routing direction conflict, path selection conflict, etc., the adjustment information can return the reason for the conflict and the policy information that can be adjusted.

[0086] Optionally, the method further includes:

[0087] Obtain the notification message related to the operation information sent by the general management function of the first virtual network function.

[0088] In this embodiment, the policy agent can be responsible for making policy decisions, such as evaluating whether policy conditions are met and deciding on the actions to be taken when the conditions are met. The policy agent can subscribe to notifications related to events executed by the corresponding GOF (i.e., the first virtual network function general management function), such as timely obtaining notifications during upgrades.

[0089] Optionally, in the method, the virtual network function general management function includes one or more of the following:

[0090] Traffic management function;

[0091] Upgrade management functions;

[0092] Log management functionality;

[0093] Notification management function;

[0094] Configuration management functions.

[0095] In this embodiment, such as Figure 5 As shown, the VNF Generic OAM functions (i.e., the virtual network function generic management functions) in the PaaS Services platform can be generalized, providing OAM management functions applicable to VNFs in a generic form. They can also simplify the work of one or more entities (e.g., VNFs) including configuration, updates (or upgrades), traffic, logs, notifications, etc., to reduce the management tasks and workload of the 3GPP management system and the NFV-MANO system architecture; or they can be classified as a special form of PaaS service.

[0096] Optionally, the method further includes:

[0097] A10, Obtain the data analysis report sent by the management data analysis function; wherein, the data analysis report includes real-time network performance data and management data of multiple virtual network function general management functions;

[0098] A20, based on the operation corresponding to the operation information, analyze the real-time network performance data and management data to obtain the general management function of the first virtual network function.

[0099] In this embodiment, such as Figure 6 and Figure 7As shown, the policy agent is responsible for interacting with the 3GPP management system and implementing relevant policies. The policy agent supports interaction with the MDAF (Management Data Analytics Function) to automatically obtain network performance and management data, analyzes the collected data, and determines the appropriate VNF General Management Function (GOF) to be invoked based on the analysis results, so as to jointly implement the relevant policies. (Note: In 3GPP, the Management Data Analytics Function (MDAF) is a key function that uses artificial intelligence (AI) and machine learning (ML) technologies to optimize network performance and management. It can monitor network performance and management data in real time, and can use AI algorithms to analyze data, such as the status of specific VNFs, the usage of virtual resources, etc., and provide a potential set of suggestions, hereinafter referred to as the data analysis report.) 3.1, the policy agent obtains the data analysis report from the management data analysis function; 3.2, the policy agent can be responsible for making policy decisions, making policy decisions based on the obtained data analysis report, such as assessing whether policy conditions are met and deciding on the operations to be performed when the conditions are met, thereby obtaining the first virtual network function general management function.

[0147] In this embodiment of the invention, the module can be implemented in software so that it can be executed by various types of processors. For example, an identified executable code module may include one or more physical or logical blocks of computer instructions, which may be constructed as objects, procedures, or functions.

Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.
